"It is a no-brainer," Derek Bennett, the chief of staff for Iraq and Afghanistan Veterans of America, said on "Fox News Sunday."

"There have been plenty of studies of IG reports of GAO reports dating back to 2008 alleging gaming of the system," he added.

The department is facing criticism of long wait times for veterans. Some facilities are accused of falsifying reports to make it appear veterans received care faster than they did.

The department's inspector general is investigating at least 26 facilities around the country after reports last month suggested nearly 40 veterans died while on a secret wait list at a Phoenix VA clinic.
